[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. During one dialysis, the patient's blood comes into contact with a large amount of dialysate through the dialysis membrane. City tap water contains various trace elements, especially heavy metals, as well as some disinfectants, endotoxins and bacteria. Contact with blood will cause these substances to enter the body, so pure water is needed. Therefore, a pure water preparation device for hemodialysis is needed to meet the water resources required during the dialysis process.
